It doesn’t look good on either Smitty or Svats coming back before the end of the regular season.
The Avs are going to announce soon that, while Smyth’s head and neck checked out well on CAT scans, the left shoulder is likely separated – but things will be officially known in the coming days.
Translation: he’s got a shoulder separation, at least. I’ve also been hearing about a possible broken collarbone – the most commonly broken bone in the human body.

As for Svatos, the Avs are saying the full extent of his left knee injury will be known in the coming days.
Translation: it’s too swollen to get an accurate reading right now. After covering a million of these kinds of injuries, this is not good news.
I would say both are done for the year. But maybe with a long playoff run, they will be back.
I hope I’m wrong, but nothing ever goes right for the Avs when it comes to injuries, so expect the worst.
